Problem with cracking Office password that contains custom character

[philsmd]

unfortunately, there is no way to fully get it without trying to learn about character encoding and what utf16le means etc.
There is no shortcut. You need to understand the way characters are represented and how ascii / utf8 chars are converted to utf16le etc:

Code:

echo -n čać | iconv -f utf8 -t utf16le | xxd -p
0d0161000701

so in this case only this would work:

Code:

--self-test-disable --hex-charset -2 0001070d61 hash.txt ?2?2?2?2?2?2

the password is 3 x 2 characters long: 0x0d01 for the utf8 character č , 0x6100 for the character a, and 0x0701 for the multi-byte utf8 character ć
